Add a function to make it easier to debug a test failure caused by an unexpected stop reason. This is similar to the assertState helper that was added in ce825e46743b. Before: self.assertEqual(stop_reason, lldb.eStopReasonInstrumentation) AssertionError: 5 != 10 After: self.assertStopReason(stop_reason, lldb.eStopReasonInstrumentation) AssertionError: signal (5) != instrumentation (10) Differential revision: https://reviews.llvm.org/D131083
